okay so im new to this and i searched a bit but couldnt find anything,
if i use my jb4 to read off my fuel and oil temp guage the (boost on fuel, timing on fuel, and air fuel ratio) what should i be looking for like what numbers should the guage be reading at when im at idle or wot etc...

just curious any input helps....

that will vary depending on mods and how aggressive the tune is, All the things you listed are variables dependent on your conditions. For example, I'm hitting 15-16 psi on my current setup but I use map 5 and have other mods. You may be on Map 1 which has a max boost of 12psi. I don't believe there is a straight answer to your question since we don't know the exact conditions you're running.

if you dont understand what it means, maybe its best if you just keep it off.

if your curious,

Boost on fuel lets say, depending on what map you run, you can see what your target boost is and your boost limit. lets say map 1 boost target is 13-14 PSI. Your fuel gauge(showing boost) should be a 0 when your at idle. You build boost when you put rev your engine or when engine is on load. Reading would be 0 mark is 0PSI, 1/2 tank mark is 10psi, and 1(full tank) is 20PSI. So your gauge should show above half way and under 3/4 tank. you'll only see 13-14PSI under wide open throttle.

Air fuel ratio on fuel gauge, would be 0 mark-10:1 1/2 mark -15:1 and full tank is 20:1. usual target is around 12-13:1 ratio. you do the math.

yea i was looking for that part where you said it should be around 12-13:1 now i know what to normally look for,
the reason i asked this is becuase my car took a s*** on me the other day and after reading the codes i had a misfire in ever cylinder besides 4 and 6 some one told me to be careful its not timing issue. thats why i wanted to see what i should be looking for if im reading timing on fuel..
